Shortness of breath. I am only on Symbicort and a rescue inhaler. I only use the rescue inhaler before I work out.
I mostly want to halt the progression of the COPD.
Two things that may help...
Standard Process makes a supplement called Cataplex E2.
This is the oxygen-sparing portion of vitamin E. It enables your body to meet its need for oxygen with less oxygen.
Second, look into Cordyceps.

It gets oxygen into your tissues, along with many other benefits.
I use both. Big difference for me.
Best.
